Surprisingly, arylhydrazones 88a-d, upon treatment with 1-benzenesulfonyl-hydrazide 89 in refluxing ethanol, afforded very good yields of pyrazol-3-ones 90a-d (85JIC54) (Scheme 25). 5-Aminopyrazol-3-(Mies have also been synthesized from /3-cyanoesters (Section II,A,2) and from /3-iminoesters (Section II,A,3). 

Methyl-2(l //)-quinoxalinone (215) gave 1 -benzenesulfonyl-3-methyl-2(l //)-quinoxalinone (216) (PhS02Cl, K2C03, AcMe, reflux 3 h 90% analogs likewise).105...

The benzenesulfonyl substituent has also been used in conjunction with the lithiation of an azaindole derivative (86FRP2574406 89FRP26274931), and thus 1-benzenesulfonyl-1//-pyrrolo[3,2-c ]pyridine was able to be successfully lithiated and alkylated with p-methoxybenzaldehyde, although reaction with more hindered ketones could not be achieved (Scheme 19)[91JCS(P1)3I73].

In the course of our investigation of 2-substituted derivatives of 5-methoxy-TVTV-dimethyltryptamine, we prepared N,-protected (i.e., 1-benzenesulfonyl) derivatives in order to functionalize the 2-position. Once the 2-position substituent was introduced, the N,-protecting group would be removed (86). One of the N,-protected analogs, compound 65, was submitted for binding and was... 

Azaindoles are more stable to air oxidation than indoles, are stable to mild reagents like silver oxide and selenium dioxide, but are readily attacked by permanganate. In the structure proof of 7-aza-indole, Kruber oxidized the 1-benzenesulfonyl derivative with potassium permanganate in acetone solution to obtain 2-(benzene-sulfonyl)aminonicotinic acid. The 1-acetyl and 1-benzoyl derivatives gave inconsistent results, which Kruber attributed to their ease of hydrolysis. l-Benzoyl-2,5-dimethyl-4-azaindole and its 3-substituted derivatives give 3-benzamido-6-methylpicolinic acid with permanganate oxidation. ...
